Tackling ozone pollution in Colorado (starts at 3:55): Cooler fall weather might soon bring back the bluebird skies we all love. But last year ozone levels in the Denver metropolitan area were high enough to prompt state health officials to issue ozone action alerts an average of once a week. (This summer has fared somewhat better.) During these ozone alerts, health officials recommend that children, the elderly and people with compromised lungs do not exercise outdoors. Hosts Daniel Glick and Susan Moran interview John Putnam, the environmental programs director for Colorado’s Department of Public Health and Environment, about the science, the sources (the largest being oil and gas operations), the health impacts, and policy approaches to ozone pollution. Governor Jared Polis named Putnam to tackle, among other things, a longstanding problem with the state’s air quality: parts of the state have been out of compliance with federal Clean Air Act standards for more than a decade. Last year, the Environmental Protection Agency upped the ante. It declared that parts of Colorado are in “serious” non-compliance of federal air quality standards for ozone, which we all know as “smog.”

Air Pollution, Possible Solutions (start time: 2:36) It is ubiquitous and essential to our life. It it is also the cause of some 7 million premature deaths around the world every year, ranking just behind diet, cancer and tobacco as a health risk. That’s the air we breath. Beijing, New Delhi, and London are among the smoggiest, but the Denver metro area isn’t faring so well either. Yet many countries and cities have taken positive steps that have dramatically reduced emissions, from vehicles, smokestacks, crop and animal production, and other sources. Our two guests today have been researching air pollution—its sources, impacts and solutions–and they share their insights and data with How On Earth’s Susan Moran and guest host, journalist Jason Plautz. Beth Gardiner, an environmental journalist based in London, authored the recently published book Choked: Life and Breath in the Age of Air Pollution. And Dr. Frank Flocke is an atmospheric scientist at the National Center for Atmospheric Research, and an author of a major study of air pollution sources on the Colorado Front Range.

Today’s show offers two features: Oil & Gas Impacts (start time: 1:05) Proposition 112, which would require oil and gas wells to be at least 2,500 feet from homes, schools, parks and other buildings, has highlighted mounting public concerns about the health, social and other impacts of extensive drilling along Colorado’s Front Range. Weld County is center stage for the latest oil and gas boom; nearly half of Colorado’s 55,000 active wells are located there. Jason Plautz, a Denver-based journalist, discussed with host Susan Moran the science and politics surrounding drilling activities, and whether explosions such as the one in Windsor last December could happen in many other locations. Plautz and Daniel Glick wrote a feature article that has just been published in High Country News.
Healthy Planet+Healthy Humans? (start time: 14:46) Matthew Burgess has been immersed in thinking about and studying how we humans, and the planet we inhabit, can both remain intact—in fact, can both thrive–well into the future. What’s he smok’in, you might ask? In fact, he is a serious environmental scientist at the University of Colorado Boulder. Dr. Burgess and nearly two dozen colleagues authored a recently published scientific paper that applies models to show how we can meet demands of increased populations and economic growth in 2050, while simultaneously achieving bold and effective conservation and climate goals set forth by the United Nations. Dr. Burgess is an assistant professor in Environmental Studies, with an additional appointment in Economics. And he works at the Cooperative Institute for Research in Environmental Science (CIRES), the collaboration between the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado. He discusses the paper and its implications with hosts Susan Moran and Joel Parker.

Today’s show offers two feature interviews: New Theory of How Cancer Evolves Inside Us (start time: 0:58): It is commonly known that cancer afflicts old people more than youth. Conventional wisdom has held we get cancer with age largely because we accumulate lots of genetic mutations over many years, and it’s the mutations that cause cancer. Our guest, Dr. James DeGregori, deputy director of the University of Colorado Cancer Center, discusses with host Susan Moran his new theory–one that challenges conventional wisdom–about why and how we get cancer. In his new book, called Adaptive Oncogenesis: A New Understanding of How Cancer Evolves Inside Us, DeGregori argues that cancer is as much a disease of evolution as it is of mutation. Mutated cells outcompete healthy ones in the ecosystem of the body’s tissues. Dr. DeGregori is a professor in the Department of Biochemistry and Molecular Genetics at the University of Colorado Anschutz Medical Campus.
Studying Health Impacts of Oil&Gas Wells (start time: 12:54) Many people living all along the Front Range are familiar with the sights and smells of oil rigs operating in fields near their homes and schools. State regulators argue that this convergence of people and oil rigs is safe. But many nearby residents and scientists are concerned about the potential health impacts of these drilling operations so close to residential neighborhoods and schools. Our guest, Dr. Lisa McKenzie, is the lead author on a new study that adds some critical evidence to back concerns of residents. It found that for people living within 500 feet of a well, the risk of their getting cancer over the course of their lifetime is eight times higher than the upper acceptable levels established by the federal EPA. Dr. McKenzie is an assistant research professor at the Colorado School of Public Health at the University of Colorado Anshutz Campus. She discusses the study and its implications with hosts Daniel Glick and Susan Moran. (Here is our interview with Dr. McKenzie a year ago about a related study.)

It’s the endless stream of tailpipes on the L.A. freeway which causes that unsightly smog, nagging cough and chronic respitory problems, right? Perhaps not any more, a new scientific study helps build the case that the major culprit may now be purchases made at the corner drug store or hardware store. Chip Grandits speaks with Dr. Brian McDonald of NOAA about perhaps changing tactics for the next stage in the human race’s campaign to keep the air clean and healthy in both the indoor and outdoor environments of the urban areas many of us call home.
A couple headlines focus on related aspects of the changing climate in our Alpine environment and what it really means. Does it seem like spring comes earlier every year, or is that just your imagination? Well, the science says probably not, especially if you live in the Northern latitudes. Science journalist Tom Yulsman, who writes about climate change and beyond in his blog ImaGeo for Discover magazine, offers a headline the declining snowpack in the Rockies.
